I have set the  dp.headerDateFormat to show locale short week day together with date pt-br format
 dp = new DayPilot.Calendar("dp");
        
         dp.locale = "pt-br";
        
         dp.headerDateFormat = "ddd - dd/MM/yyyy";
Header show the correct date format, but ddd render using english locale option:
Sun 18/08/2016.
It should show:
Dom 18/08/2016
Can you help me to set it the correct way ?
